Grape Juice - As Good as Wine?

Grape Juice is good for you

This author has surmised for some time now that if wine is good for you, then why not the source of the wine, grapes, be good for you too?  I now guess that my perspective may be vindicated by the attached article.  (Don't get me wrong, I'd rather stay healthy with wine than juice, but heck, prevention is prevention!)
Grape juice seems to have the same protective effect against heart disease as red wine, French scientists at the Universite Louis Pasteur de Strasbourg say.
Red wine and certain types of grape juice have high levels of polyphenols, which block the production of a protein linked to cardiovascular disease -- the number one killer in many Western countries.
The team doing the research found that polyphenols in Concord grape juice activate endothelial cells to produce nitric oxide which helps to protect against cardiovascular disease, but they have not discovered which grapes have the higher concentration of the good stuff.  (I don't mean alcohol!)
